Au'ro uromarrc SPEED nnuna'ron,

Application fled l iove nber .Be it known that I, .WILLIAM S;

Jones, a citizen of the United States, re- 'sidin atRedding, in :the county of Shasta Jand tate of California, have invented certain new and useful Auto Automatic Speed Re ulators; and I do hereby declare the V fol owing to be a-full, clear,iand exact de- ":scription of the invention, such as will en- .10 appertains to make and use the same.

able others skilled in the art to which it In the operation of motor vehicles the driver must be constantly on the alert to feed the proper amount of fuel .to the engine in order to maintain an approximate uniform speed, this being necessary because of the different grades encountered in negotiating the average thoroughfare and this entails frequent adjustment of the throttle.

The purpose of the present invention is the provision of means mounted upon the vehicle and connected with the throttle and the throttle lever, whereby the adjustment of the throttle to maintain an approximate given speed is automatic, so that when ascending a grade-more fuel is supplied to the engine to compensate for the extra load and when descending a grade the supply of fuel to the engine is proportionately reduced to compensate for the reduction in load, the several adjustments being efi'ected automatically and proportionately to the variation of the load, with the result that the vehicle is caused to travel at a practically uniform speed.

Other objects and advantages Will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the specification,

tionof'the arrows and i Figureis 'a' horizontal sectional view on the lines-+5 of Figure 4. I Gorre'sp'onding and like parts are referred of Figure 3 looking in the direc-- to in the following description and designated in the several'views of the drawings by like reference characters.

The". numerals 1 and 2 designate a carbureter and intake manifold respectively, of conventional-type provided for the internal combustion "engine of a motor vehicle. The numeral 3 designates the stem of the usual throttlevalve 4. and this stem is provided with an arm 5 which in accordance wlth the present mvention is adapted to be 'adjustably connected to a pendulum 6 which is carried by a frame 7 adjustably mounted upon a support 8 and. which is adapted to be set by the driver in substantially the same manner as the spark or throttle of A rod 9 adjustably connects the pendulum 6 and throttle arm 5 since one end of said rod may be selectively posltioned in any oneof a series of openings 5 in said arm. The specific formation of the connection 9 will depend largelyupon the location and arrangement of the parts; The frame 7 is slidably mounted upon the support 8 and in the preferable construction the latter consists of a plate having opposite longitudinal edge portions inturned to provide guides 10 which receive lateral extensions at the foot of the frame 7. 'It is to be understood that the support 8 may be of any preferred COllSilllCi'lOl'l and mounted in any convenient position and as shown it is attached to or may form part of a plate 11 'whicl'ris adapted to be clamped between ghiadflan-ged endsof the carbureter and'mani- The adjustable frame 7 may be of any determinate construction and mounted in any preferred way so long as it forms a support for the pendulum 6 and is adapted to be adjusted from the drivers seat of the motor vehicle, and as shown'a link 12 connects the frame 7 to a bell crank 13 pivoted at 14 to the support 8. A. connection 15 forms means between the bell crank 13 and the usual throttle lever (not shown) mounted upon the steering wheel or steering post of a motor vehicle, and which provides for adjustment of the frame 7 according to the desired speed, it being remembered that the pendulum 6 carried by the frame 7 has connection with the throttle to determine the position thereof. Under normal conditions, that is, when the vehicle 1s travehng upon a level surface the throttle vmaintains the predetermined adjusted posltion, but

when the vehicle encounters-a grade, thependulum effects an opening of the throttle which results in more fuel being supplied to the engine to compensate for the additional load, and when the vehicle descends an incline the pendulum automatically oper-.

ates to reduce the supply of fuel to the engine thereby preventlng an acceleration of speed due to a decrease in the load. It

will thus be understood that the device is automatic in action in augmenting or reducing the supply of fuel to the engine, there; by resulting in the vehicle mamtaining a practically uniform speed" under various grade conditions of the road Without-the necessit of the driver being on the alert to manipu ate the throttle in the accustomed vision is had for properly setting the regulator. v I

2. Means for automatically regulating the speed of. a vehicle, the same consisting of a pendulum connected with the throttle of the engine to automatically open or close the same depending upon the load incident'to ascending or descending a grade, and a frame carrying said pendulum adjustably mounted relatively to the throttle operating means.

a 3. An automatic speed regulator of the character specified comprising a support, a

frame slidable upon the support, a pendulum carried by the frame, connectln means.

between the pendulum and thrott e, and means undercontrol of'the driver for adiusting the pendulum frame and holding the's ame in the required adjusted position.

y; 4. An automatic speed regulator com risa supporting plate having an attac ing flange projecting therefrom, arframe slidably mounted upon the supporting plate, means under control of the driver for adjusting and holding the frame in the requiredadjusted position,- a pendulum carried by said frame, and connecting means between the pendulum and throttle.

In testimony whereof I aflix my signa-- ture.
